Coding Hotstagram, which asks users to rate two photos plucked
from Instagram, took Kirk a weekend. Instagram users
who'd like to get rated can add the hashtag "#hotstagram" to
automatically submit their photos. And Kirk just added a feature
which lets people remove their photos in case they'd rather not
appear on the site.

Isn't he worried Instagram will shut down the site? Kirk says
he's read Instagram's terms and is confident he's in compliance.

Hotstagram, which was teased on
Twitter by blogger Ben Parr, appears to be a hit. Kirk says
he's seeing 150 ratings a second.

(Hot or Not, by the way, is still
alive—and is now run by Badoo, a dating-oriented social network which
recently hired high-profile Google executive Ben Ling as COO.)
